This is a video of my Octopus Briareus purchased from Tom's Caribbean immediately after being introduced to the tank. It has eaten several crabs and made a couple of dens for himself, but as of now, 48 hours after acclimation, it has not come out of hiding. The octopus is likely 6-8 months old with a mantle size of 2.5 inches and tentacle span of 20-24 inches.
